ELECTRIC HAIR SINGER.

Application filed July 14, 1928. Serial No. 292,794.

The present invention relates to improvements in an electric hairsinger, which is hereinafter fully described and claimed. and isillustrated in the accompanying drawings, in which Figure 1 is a planView of a hair singer according to the invention, and,

Figure 2 is a longitudinal sectional view, one section of the handlehaving been removed.

The main object in this invention to provide a hair singer which iselectrically heated, and in which the heating element may readily beremoved like a lamp in a socket, and replaced by a new one, should itburn out.

Another object is to provide a device of this character that will bemost simple in construction, and cheap to manufacture.

Referring to the drawings 1 is a handle comprising two hollowlongitudinal sections, one end 2 of which is enlarged to form a socketadapted to receive the removable core 3 carrying the heating element.The two sections 1 of the handle are secured together by means of thescrews 4, and 5 are holes in each of said enlarged portion. 2.

The element carrying member or core 3, consists of an elongatedporcelain member centrally bored at 6, having an enlarged base portion 7which is adapted to co-act with the socket 2. The outer periphery oi"-the memher 3 is threaded to receive a resistance wire 8 which is woundupon said thread surface, passing at one end through the aperture 10 inthe base 7, and at its other end passing through the hole 9 adjacent theouter end of said member 3, into the hollow portion 6. Both ends of saidresistance wire 8 are suitably connected to their respective poles 11and 12, carrying the outwardly projecting arms 13 and 14 which areadapted to engage the fixed contact members 15 and 16, and thus securingin firm position the core 3.

The contact members 15 and 16 are secured to the block 17, mounted inthe inner end 01 the socket 2, by means of the screws 18 and 19 whichproject through said block. Upon said block is mounted the bracket 20,and 21 is the switch operated by the push member 21 whichis slidablymounted in said bracket, and the said switch member carries the slidingcontact member 22, which co-acts with the screw 19.

The electrical energy is supplied by means of the electrical conductors23 and 2 1 which are respectively connected to the screw 18 and thesliding contact member 22.

The electrical circuit is as follows when the switched member isoperated. The energy passes from the conductor 23 through the screw 18,the contact member 16, the screw 19, the sliding contact member 22, theconductor 2d. Both conductors pass through a suitable opening 25 in theend of the handle and are connected to any suitable source of electricalenergy.

What I claim as my invention is 1-- An electric hair singer compr ing ahandle having a socket formed at one end, a removable core ofnon-conducting material adapted to engage in said socket means to securesaid core in said socket a resistance element wound around the corehaving its terminals connected to said securing means of said core,electric conductors adapted to be connected to said securing means 01said core, and means on said handle for controlling the current flowfrom said conductors to said resistance element.
